The Lowdown

Alright, Rusty here with the imperial version. Let’s break it down for Jaconé.

First surf worth mentioning comes Monday morning, August 17th. Jaconé has clean 4ft south swell, 11-second period, with offshore ENE wind at 16 mph. Wave energy is moderate at 425. It looks tidy. Afternoon shifts cross-off and gets messy.

Tuesday the 18th morning is clean with 3ft east swell, but only 7 seconds – shorter period, less push. Energy drops to 241. Light offshore NE breeze at 6 mph keeps the surface good. Wednesday and Thursday mornings offer rideable waves around 3ft to 4ft, but low energy and short period mean it’s pretty average.

Friday August 21st morning is the real highlight. Jaconé gets 6ft of ENE swell at 8 seconds, combined energy of 515. Winds go glassy calm from the WNW at 3 mph. That’s dead flat water – perfect clean conditions. This is your morning to charge. Afternoon goes onshore rubbish.

Saturday the 22nd is blown out. Sunday the 23rd recovers – 5ft SSW swell, 10 seconds, light cross-off east wind. Clean and chest-high.

Now the big one: Tuesday August 25th morning is for experts only. Jaconé sees a powerful 8ft SSW groundswell with a long 12-second period. Energy hits 1929 – very strong. Cross-off ENE wind at 9 mph keeps it rideable but this size is no joke. If you’re not experienced, stay on the sand. Wednesday morning the 26th drops to a still-chunky 5ft with offshore breeze – good for strong intermediates.

After that, the swell fades. A few clean mornings, like Sunday August 31st with 5ft south swell and light wind, but the power’s gone. September 1st finishes onshore.

To sum it up: Friday August 21st morning is the best all-around session – clean, glassy, fun. Tuesday August 25th is the big groundswell for the brave. Water temp is about normal for the season.

Rusty out.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
